Vortex-core Majorana coupling to a chiral edge in a superconductor: Nonmonotonic spectral reorganization and coherent fermion-parity dynamics
Peiyao Liu, Yi Zhou
We study how vortex--edge coupling reorganizes the low-energy sector of a finite two-dimensional \(p_x+ip_y\) superconducting disk as a function of the vortex--boundary separation…

Apparent double- from a single BKT transition in anisotropic phase-only models
Pei-Yuan Cai, Yi Zhou
Transport experiments on two-dimensional superconductors often yield direction-dependent transition temperatures, raising the question of whether such a ``double-'' reflects a…

Geometric Rashba Control of Polar Pairing at a-LaAlO/KTaO Interfaces
Yi Zhou
At amorphous-LaAlO/KTaO interfaces, superconductivity coexists with switchable polar nanoregions (PNRs), and depends quasi-linearly on crystallographic orientation. W…
